Description

TECHNICAL FIELD

[0001] The present application relates to a quick leveling device for photovoltaic panel installation and a construction method. BACKGROUND

[0002] With the transformation of global energy structure and the rapid development of renewable energy, photovoltaic power generation technology has been widely used due to its clean and sustainable characteristics. Photovoltaic panels, as the core components of photovoltaic power generation systems, their installation quality directly affects the power generation efficiency and system stability. In the actual installation process, due to the different inclinations of building roofs, ground or support foundation, the leveling of photovoltaic panels becomes a key link. The traditional photovoltaic panel installation method usually uses fixed supports or simple adjustable feet, which has low adjustment accuracy, poor adaptability and low construction efficiency. Especially when installing on complex terrain or non-standard building structures, it is difficult to quickly and accurately adjust the level of photovoltaic panels.

[0003] Currently, the photovoltaic panel leveling devices on the market mainly rely on bolt adjustment or gasket compensation, which is not only cumbersome to operate, but also has limited adjustment range, making it difficult to meet the needs of different inclined walls and complex installation environments. In addition, the traditional photovoltaic panel angle adjustment mechanism mostly uses single-point adjustment, which can easily lead to uneven stress on the photovoltaic panel, affecting the structural stability, and even reducing the service life of the photovoltaic panel due to long-term stress concentration.

[0004] Therefore, there is an urgent need for a new type of photovoltaic panel quick leveling device and construction method, which can realize multi-stage gear adjustment of the feet to adapt to different angle installation base surfaces, while having independent adjustment function at both ends of the photovoltaic panel, improving the leveling efficiency and installation flexibility, and thus improving the overall performance and reliability of the photovoltaic system.

DETAILED DESCRIPTION

[0040] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0041] In the description of the present application, the terms "first", "second" are only used for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0042] Embodiment one

[0043] Referring to Figures 1-2 As shown in the drawings, a quick leveling device for photovoltaic panel installation includes a base plate 10, an upper plate 50, a support plate 70 and a photovoltaic panel body 90. The base plate 10 is symmetrically provided with a sliding groove 40 on both sides of the top, and a sliding baffle 20 is slidingly connected to the sliding groove 40.

[0044] Specifically, the sliding baffle 20 not only serves as an auxiliary positioning structure for the installation of the photovoltaic panel, but also has an aerodynamic optimization function. When the photovoltaic panel body 90 is installed in place, the extension length and position distribution of the two sliding baffles 20 along the sliding groove 40 can be flexibly adjusted according to the local wind direction characteristics. The spoiler structure formed by the baffles effectively decomposes the frontal wind pressure and reduces the wind vibration effect. The edge of the baffle is designed with a flow guide slope, which blocks the direct impact of strong wind on the edge of the photovoltaic panel while guiding the airflow smoothly through the gap between the panel surfaces, achieving a dynamic wind breaking effect. This sliding adjustable baffle design not only maintains the lightweight characteristics of the installation structure, but also significantly improves the wind lifting resistance and operational stability of the photovoltaic panel system in severe wind environments.

[0045] It should be noted that the actual size of the sliding baffle 20 and the actual size of the photovoltaic panel body 90 need to be designed according to actual data. The size of the sliding baffle 20 and the size of the photovoltaic panel body 90 in this case are not set precisely.

[0046] Referring to Figure 1 , 3 , 8 and 9, the base plate 10 is provided with four groups of gear type rotating support mechanisms 30 distributed at the four corners of the bottom, and each group of gear type rotating support mechanisms 30 is independently adjusted at multiple angles; the gear type rotating support mechanism 30 includes a support base 300, a pair of lower side plates 301 with shaft holes are symmetrically arranged at the top of the support base 300, a universal joint 302 penetrates the shaft holes of the lower side plates 301, first gear pieces 303 are fixed at the axial ends of the universal joint 302, upper side plates 304 are rotatably arranged on the universal joint 302, a fixing piece 305 is arranged between the two upper side plates 304, an upper mounting plate 306 is fixed between the upper side plates 304 through the fixing piece 305, and a second gear piece 307 is integrally formed on the lower surface of the upper mounting plate 306 and meshes with the first gear piece 303, so as to realize the rotational adjustment of the support base 300 relative to the upper mounting plate 306, and the base plate 10 can adapt to different angle installation wall surfaces. It should be noted that the first gear piece 303 and the second gear piece 307 are made of nylon or spring steel material, and when swinging, the gear tooth surface elastically deforms to maintain meshing. Further, the upper side plate 304 is additionally provided with a swing angle limiting groove to avoid tooth disengagement caused by excessive deflection.

[0047] Referring to Figures 8-9 , the present case also includes an adaptive adjustment of the gear type rotating support mechanism 30 to the Y-shaped wall and the inclined roof slope of the inclined wall:

[0048] Y-shaped wall installation condition:

[0049] The Y-shaped wall usually has a certain bifurcation angle, and its shape is similar to the letter "Y". This structure can be used for specific space division or decorative effect in buildings;

[0050] The gear-type rotating support mechanism 30 can adapt to the complex angle requirements of Y-shaped walls through its multi-angle adjustment function. Specifically, the four sets of gear-type rotating support mechanisms 30 at the bottom of the base plate 10 can be independently adjusted at multiple angles, allowing the base plate to closely fit each bifurcated surface of the Y-shaped wall. The meshing transmission of the first gear part 303 and the second gear part 307 can achieve rotational adjustment of the support base 300 relative to the upper mounting plate 306, allowing the base plate 10 to flexibly adjust the angle to adapt to the angle changes of different branches of the Y-shaped wall.

[0051] The design of this support mechanism allows the base plate 10 to quickly find the appropriate angle when installed on a Y-shaped wall, reducing the adjustment time and labor intensity during installation, while improving the installation precision and stability.

[0052] Inclined wall roof slope

[0053] Roof slopes usually have a certain inclination angle, and their design is mainly for drainage, aesthetics, or to meet specific architectural functions. The roof slope angles of different buildings may vary, so the installation equipment needs to be able to adapt to multiple angles;

[0054] The gear-type rotating support mechanism 30 can adapt to the installation of roof slopes with different slopes. Through its unique gear meshing and rotational adjustment mechanism, the base plate 10 can flexibly adjust the angle to match the inclination angle of the roof slope. The first gear part 303 and the second gear part 307 are made of nylon or spring steel, which can maintain elastic deformation of the gear surface when swinging, thereby maintaining stable meshing state at different angles;

[0055] During the installation of the roof slope, the multi-angle adjustment capability of the gear-type rotating support mechanism 30 can ensure that the base plate 10 closely fits the slope surface, avoiding the installation being not firm or unstable due to angle mismatch. In addition, the swing angle limiting groove design on the upper side plate 304 can effectively prevent over-deflection from causing tooth disengagement, further improving the safety and reliability of the installation.

[0056] Reference Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, the top of the substrate 10 is provided with an angle adjusting mechanism 60, which is detachably connected with the photovoltaic panel body 90 and realizes the pitch angle adjustment thereof; the angle adjusting mechanism 60 comprises a positioning base 600 fixed on the top of the substrate 10, guide grooves 6000 provided on the two sides of the positioning base 600, an I-beam 602 provided in parallel with one end of the length direction of the positioning base 600, a lead screw transmission assembly penetrating through the I-beam 602, the lead screw transmission assembly comprising a lead screw 6024 penetrating through the I-beam 602 and a hand wheel 6022, an upper positioning sliding seat 6002 fixedly arranged on the positioning base 600, a sliding frame 604 slidingly arranged on the upper positioning sliding seat 6002, and a four-bar linkage angle adjusting assembly cooperatively connected with the sliding frame 604.

[0057] The four-bar linkage angle adjusting assembly comprises first tilting arms 606 symmetrically hinged on the two sides of the sliding frame 604, a positioning rod 6060 and a first connecting rod 6066 connecting the sliding frame 604 and the first tilting arms 606, side fixing plates 6082 for fixing the first tilting arms 606 and the positioning rod 6060, a shaft ring 6084 arranged on the side fixing plates 6082 and sleeved with the positioning rod 6060, pivot connecting seats 608 arranged on the adjacent sides of the I-beam 602, a second connecting rod 6080 arranged between the two pivot connecting seats 608, a second tilting arm 6086 rotatably arranged on the second connecting rod 6080, connecting plates 610 symmetrically arranged on the other ends of the two first tilting arms 606, third connecting rods 6102 for connecting the connecting plates 610 and the two first tilting arms 606, and movable mounting grooves 6100 formed on the connecting plates 610; the first tilting arms 606 and the second tilting arm 6086 are linked through the first connecting rod 6066 to form a parallelogram lifting mechanism; the positioning rod 6060 is sleeved with a guide column 6064 slidingly connected with the guide grooves 6000.

[0058] The gear type rotary support mechanism 30 and the angle adjusting mechanism 60 constitute a cooperative adjustment system to jointly maintain the horizontal reference plane and the preset inclination angle of the photovoltaic panel body 90.

[0059] Referring to Figures 6-7 As shown, a clamping mechanism 80 is arranged on the top of the support plate 70 and is used for clamping and fixing the photovoltaic panel body 90; the clamping mechanism 80 comprises a clamping base 800, edge clamps 8000 formed on the clamping base 800, an inner ring base 802 rotatably arranged in the middle of the clamping base 800, a handle 8020 fixedly arranged on the inner ring base 802, a spiral groove 8022 formed on the inner ring base 802, a sliding block 8024 slidingly arranged on the spiral groove 8022, a clamping piece 8026 fixedly arranged on the top of the sliding block 8024, and a central shaft 8028 arranged in the middle of the clamping base 800 and the inner ring base 802; the top of the clamping base 800 is provided with a positioning ring plate 804, an adaptive groove 8040 formed on the positioning ring plate 804 and slidingly connected with the clamping piece 8026, and an auxiliary piece 806 arranged on the top of the positioning ring plate 804.

[0060] Specifically, the linkage logic of the gear type rotating support mechanism 30 and the base plate 10 is as follows;

[0061] When the installation surface has an inclination angle, the support base 300 is subjected to a tilting force and is deflected, and the linkage process is as follows: due to the inclination of the installation surface, the angle of the support base 300 in contact with the ground surface changes, causing the universal joint 302 to deflect, the universal joint 302 allowing the support base 300 to swing left and right by ±15°, while the axial rotation force is transmitted to the first gear parts 303 at both ends, the first gear parts 303 rotate and engage with the second gear parts 307 of the upper mounting plate 306, pushing the second gear parts 307 to rotate, the gear tooth surfaces can be slightly elastically deformed to ensure that they remain engaged during swinging, avoiding jamming or tooth disengagement, the rotation of the second gear parts 307 drives the upper mounting plate 306 to deflect axially around the universal joint 302, compensating for the inclination angle of the installation surface. Thus, the four sets of gear type rotating support mechanisms 30 independently respond to inclination angles in different directions, automatically adjusting the angle height through gear transmission, so that the base plate 10 restores to horizontal, while the swing angle limiting groove limits the maximum deflection angle of the upper side plate 304, preventing excessive swinging from causing the gears to disengage.

[0062] The linkage logic flow chart is as follows:

[0063] Inclination of the installation surface

[0064] ↓

[0065] Deflection of the support base 300 → rotation of the universal joint 302

[0066] ↓

[0067] Rotation of the first gear parts 303 → engagement of the second gear parts 307

[0068] ↓

[0069] Angle adjustment of the upper mounting plate 306 → dynamic leveling of the base plate 10

[0070] ↓

[0071] Four sets of mechanisms cooperate to compensate → maintain the horizontal reference plane within ±0.5° error.

[0072] The linkage logic of the angle adjustment mechanism 60 and the photovoltaic panel body 90 is as follows,

[0073] Hand wheel 6022 drive → lead screw 6024 advance → four-bar linkage angle adjustment assembly deployment → precise adjustment of the pitch angle of the photovoltaic panel:

[0074] Rotating the hand wheel 6022 drives the screw rod 6024 to rotate, pushing the sliding frame 604 to move linearly along the guide groove 6000, and the displacement of the sliding frame 604 pulls the first inclined arm 606 through the first connecting rod 6066, and the first inclined arm 606 and the second inclined arm 6086 form a parallelogram linkage through the second connecting rod 6080, the guide column 6064 slides in the guide groove 6000 to constrain the movement trajectory, the connecting plate 610 is driven by the third connecting rod 6102, and the inner diameter of the movable mounting groove 6100 is greater than the outer diameter of the third connecting rod 6102, so that the third connecting rod 6102 can move in the movable mounting groove 6100 and drive the photovoltaic panel body 90 to adjust.

[0075] The cooperative logic of the clamping mechanism 80 and the leveling system is as follows,

[0076] Rotating the handle 8020 drives the spiral groove 8022 radially, and the clamping piece 8026 is synchronously clamped / released:

[0077] When the handle 8020 is rotated, the spiral groove 8022 of the inner ring seat 802 forces the slider 8024 to slide radially along the central shaft 8028, and the clamping piece 8026 is guided by the adaptive groove 8040 to move synchronously centripetally, realizing four-point synchronous clamping.

[0078] Linkage effect: single-side operation can balance the clamping force. The pressure sensor feedbacks to the handle LED lamp, and the red light alarms when overloaded. The figure is not shown, which can be set according to actual needs in actual application.

[0079] System linkage innovation three-level cooperative control logic

[0080] Wall surface inclination compensation → substrate leveling → photovoltaic panel fine adjustment → clamping and fixing

[0081] ↑Gear type rotating support mechanism 30 ↑ Angle adjustment mechanism 60 ↑ Clamping mechanism 80

[0082] The horizontal state of the substrate 10 is fed back to the angle adjustment mechanism 60 through the inclination sensor (the figure is not shown). If the substrate 10 is inclined due to wind load, the system automatically triggers the screw rod 6024 to fine-tune, maintaining the preset inclination of the photovoltaic panel. The gear type rotating support mechanism 30 is responsible for macro reference surface adjustment, and the angle adjustment mechanism 60 is responsible for micro angle optimization. The two achieve function decoupling through independent control, but form a cooperative contrast through the physical connection of the substrate 10, and the efficiency is improved by 40% compared with the traditional single adjustment mode.

[0083] In summary, the present application realizes multi-stage motion conversion from the wall surface to the photovoltaic panel through the composite transmission chain of gear parts + four-bar linkage + helical groove, the gear type rotary support mechanism 30 and the angle adjusting mechanism 60 form cascade compensation, and respond to the deformation of the installation surface and the wind load disturbance, the hand wheel 6022 is integrated with a force feedback module which is not shown in the figure, and can be set according to actual needs, and when the mechanism reaches the limit position, the tactile prompt of automatically increasing the rotary resistance is provided.

[0084] Among them, the macro leveling of the substrate 10 is realized by the four groups of gear type rotary support mechanisms 30 at the bottom, when the installation wall surface is not flat, the universal joint 302 drives the first gear part 303 to rotate, is engaged with the second gear part 307 at the bottom of the upper mounting plate 306, the elastic deformation characteristics of the nylon / spring steel material gear are used to maintain the engagement, and the limit groove of the upper side plate 304 is used to prevent tooth disengagement, so that the support base 300 can be deflected in multiple directions to adapt to different inclined wall surfaces; the angle adjusting mechanism 60 at the top of the substrate 10 drives the lead screw 6024 through the hand wheel 6022 to drive the sliding frame 604 to move along the upper positioning sliding seat 6002, and drives the four-bar linkage angle adjusting assembly to slide along the guide groove 6000 through the positioning rod 6060 and the guide column 6064, and the first connecting rod 6066, the second connecting rod 6080 and the third connecting rod 6102 form a parallelogram transmission, so that the connecting plate 610 drives the support plate 70 to rise and fall through the movable mounting groove 6100, and the pitch angle of the photovoltaic panel body 90 is finely adjusted; the clamping mechanism 80 drives the inner ring seat 802 to rotate through the rotating handle 8020, the helical groove 8022 drives the sliding block 8024 to move radially, and the clamping part 8026 slides along the adaptive groove 8040 of the positioning ring plate 804 to clamp / loosen the edge of the auxiliary part 806, finally the gear type rotary support mechanism 30 and the angle adjusting mechanism 60 cooperate to maintain the horizontal reference plane and the preset inclination angle of the photovoltaic panel, and the rapid leveling and fixing are completed.
